Theoretical particle physics is the development of models for describing fundamental particles and their interactions. This includes testing and refining the prevailing theory: the standard model.

Does gravity act equally on all particles in the universe, or are there differences between ordinary and exotic matter? Physics professor Anna Soter and her team at ETH Zurich and the Paul Scherrer ...

Particle physics is the study of the elementary building blocks of matter and radiation and their interaction. The fundamental particles are summarised by the standard model. This includes leptons ...

The European Organization for Nuclear Research, or CERN, will dismantle the Large Hadron Collider, which helped discover the so-called God Particle, in order to build a more powerful particle ...

Particle astrophysics is a research area at the interface of particle physics, astrophysics, and cosmology that investigates fundamental particles and their interactions using astrophysical sources ...

PM stands for particulate matter (also called particle pollution): the term for a mixture of solid particles and liquid droplets found in the air. Some particles, such as dust, dirt, soot, or smoke, ...

Under the Clean Air Act, the EPA sets national ambient air quality standards (NAAQS) for particulate matter (PM) at levels that are safe for public health and the environment. PM 10 describes ...

We may have finally spotted a dark matter particle – but figuring out exactly what kind of particle it was is a daunting task. Even as researchers race to confirm they really did detect an unknown ...

After decades of debate, the scientific case is clear for Europe’s Future Circular Collider, a colossal successor to the Large Hadron Collider. But transforming this megaproject from vision to reality ...
